Stainless steel one

250L and 1000 L industry stainless steel biogas desulfurizer and dehydrator tower





In purifying performance and operation, the desulfurization equipment is with

1) reasonable structure

2) small bed resistance

3) high sulfur removal

4) easy operation

5) high sulfur capacity penetration

6) strong adaptability of installation site
7) no secondary pollution

8) simple and quick installation etc.




Product Description

1. Biogas desulfurization equipment is mainly to remove H2S and impurities in biogas. Fill desulfurizer in desulfurization equipment to remove H2S.  

2. Desulfurizer in the desulfurization equipment, the components are mainly Ferric Oxide, and add other efficient purifying material from the processing of additional accelerator. Even in no oxygen and no ammonia environment, it also can remove H2S precisely. It also has effect on removal of thiols organic sulfur and most of the nitrogen oxides.


3. Main physical and chemical properties of desulfurizer:  1KG desulfurizator can purifier 200m3 biogas 



AppearanceBrown cylindrical bar
DimensionsDia5 to 6 Len. 5 to 30mm
Ferric Oxide content25 to 33 percent
Density0.85kg per Litre
Porosity50 to 60 percent
IntensityNot less than 50.0N per cm(Lateral pressure)



Pay attention to

1. Do remove the crumb firstly, after pouring out the material of desulphurizer, just remain the
granular material.
2. Do not put the material on the plastic or wooden or inflammable products when regenerating.
3. Do not put the crumb material of desulfurizer back to desulphurizer


Working principle:

When biogas comes out from plant, there are some steams which can be departed through cooling. The principle of desulfurization: Fe2O3.H2O+3H2S=Fe2S3.H2O+3H2O

after used some times, sufficiency of desulfurization would be decrease. Then we should replace
desulfurization or regenerate. The principle of regeneration: 2Fe2S3.H2O+3O2=2Fe2O3.H2O+6S
